ALSA: emu10k1: remove pointless displacement of the extra voices

The idea is to make the extra voice lag behind the "real" voices, but
moving the buffer address around doesn't contribute to that, as the CCCA
write below uses the same address. The exact address is unimportant, as
the data is discarded anyway.
